Yeah, that's your problem.

To correct a left or right problem like that, you'll be changingthings like draw weight, or point weight, or arrow length, rest position, or rest tension.

Go to Easton's websight and download their tuning guide. Just remember that it is written for a right hander, so your solutions will be the opposite of what is recommended. If they say to move your rest to the left, you'll have to go right.

Other things to consider...
Have you paper-tuned or bare-shaft-tuned with field points? (do that first)
Do your broadheads spin true on the shaft? (if not, fix that first)
Are you shooting groups, and not individual arrows? (always shoot groups to eliminate as much shooter induced error as you can)

When everything is humming along like it should, your field points and broadheads should hit the same spot atall resaonableranges.
